Back to 1980: Please Love Me Again

Chapter 325 Produced by Jingyun Group, it must be a boutique

Shanqian Village, Jingyun Battery Factory.

Lead-acid batteries allow people to store electrical energy for the first time like storing vegetables and fruits. It has a history of more than 1859 years since its birth in 100.

The charging and discharging process of lead-acid batteries is actually the process of converting electrical energy into chemical energy and storing it and converting chemical energy into electrical energy and releasing it, mainly involving the conversion of lead sulfide and lead dioxide.

The main raw materials used in the production of lead-acid batteries are high-purity lead alloy grids, electrolytes prepared with high-purity concentrated sulfuric acid and distilled water, positive and negative materials lead dioxide and sponge lead, and battery casings.

Ye Luzi of Jingyun Battery Factory is a monk, and he certainly does not have his own production capacity of sulfuric acid and lead alloys, so the core raw materials are currently purchased from outside.

Zhao Wenmu has been looking for relatively good sulfur mines around the world, as well as lithium ore resources that will be very important in the future.

If you buy it now, you will earn a fortune in the future!

Especially lithium ore.

Lithium resources are worthless at the moment.

Even if the raw materials are purchased, Jingyun Battery has made some innovations in the design, such as optimizing the commonly used rectangular grid into a net-washing grid, which is actually the technology that Sakura Country is currently improving.

While effectively improving the conductivity, the corrosion of the lead-antimony alloy grid by the sulfuric acid electrolyte is minimized.

Thereby prolonging the service life of the battery.

"XCMG, is there any good solution to the battery 'starvation' problem?"

Facing the highly paid professionals hired by the battery factory, Zhao Wenmu expressed his doubts.

"Starvation" of lead-acid batteries means that if the battery is left idle for a long time, it will seriously lose power, and it will not be able to charge, and it will not be far from being scrapped.

Therefore, lead-acid batteries should be charged and discharged regularly when not in use.

This problem had troubled him for many years in his previous life, and later he stopped using lead-acid batteries when he was rich enough, so he stopped paying attention to it.

I don't know if the industry has finally solved this problem.

"Boss Zhao, the starvation phenomenon is actually caused by the vulcanization of the lead-acid battery plate, forming lead sulfate crystals, which makes the original chemical reaction unable to continue, and thus cannot be charged. At present, there is no good way to prevent this phenomenon. Structural innovation is a way of thinking, but generally speaking, it is a temporary solution rather than a permanent cure.”

"For users, it is most practical to charge and discharge in time and maintain the battery properly. If the sulfuration is not serious, using high-voltage current-limiting charging and updating the electrolyte can almost save it."

Engineer Xu has a deep understanding of lead-acid batteries, and he does not rush to answer various questions.

"Does the lead-acid battery have a memory effect?"

Zhao Wenmu continued to ask.

"Memory effect?"

Xu Gong showed a puzzled expression on his face. He had never heard of this term in the field of lead-acid batteries.

"That is to say, the battery must be fully charged for the first few times of charging, otherwise it will not be fully charged in the future."

Zhao Wenmu clearly remembers the years when the mobile phone first came out, everyone said so.

Of course, the mobile phone is definitely not a lead-acid battery, but will the lead-acid battery also have this problem?

"Oh, lead-acid batteries don't have that problem."

In fact, the memory effect is a problem with nickel-chromium batteries, which were used in early mobile phones.

In a few years, this XCMG will conduct research on this issue.

Zhao Wenmu came here this time mainly to look at their super bright lanterns.The shape of this portable lamp was designed by himself, and it looks a bit like a portable teapot overall.

Of course, it is angular and square.

The cuboid-shaped main part is actually a small lead-acid battery, with an ergonomic handle on the top, a detachable lamp head in the front, and a flip-up lamp cover in the back.

There is a small light bulb at the front and back, the front light bulb is brighter, and the back light bulb is slightly less powerful.

The pattern on the side was hand-painted by Zhao Jing herself.

A round and cute juvenile giant panda is lying on the ground with all fours in the air, holding a big bamboo shoot in both hands, showing off wildly.

The whole picture is vivid and fully depicts the cuteness and cuteness of the juvenile giant panda.

Let this portable lamp win the love of many children.

Of course, this may not be a good thing for the lantern itself.

There are many 'innocent' lanterns that have been destroyed by children, who gradually ran out of power or burned out the bulbs in their constant play.

What's more, the child accidentally dropped it on the ground and broke one side of the lamp.

Yes, of the two that Zhao Wenmu brought home, one of them was broken by the little girl.

After Zhao Wenmu brought home the two lanterns, the little girl became very interested in them.Even put them on the table to light up at dinner time, even though there is no power outage in the house.

Until she accidentally fell while holding the lantern.

The little guy's knees were broken, but the first thing she did when she got up was to check whether the lantern was broken.

Seeing that the raised lampshade behind the lantern had been broken, the little girl began to cry.

"Dad, I'm sorry, I broke the lamp."

It made Zhao Wenmu feel distressed for a while.

Normally, the little guy would have blown his knees and acted like a spoiled child, 'Daddy hurts'.

At this moment, she was holding the lantern and weeping silently, and it was obvious that she was really distressed.

Zhao Wenmu immediately went to Jingyun Battery Factory to bring back a box.

In this day and age, this lantern is undoubtedly an extremely attractive product.

The first is its special appearance.

Nowadays, almost every household has a tin flashlight, and even this is the only "electrical appliance" in many households, so let's call it an electrical appliance.

And this big portable lamp, just the shape is enough to attract attention.

What's more, its brightness is far more than that of a flashlight!
There are still many rural areas without electricity at the moment. As for places with electricity, power outages are commonplace.

The penetration rate of flashlights should be similar to that of mobile phones in 2020.

Many people were eating dinner when the power went out suddenly. Although it would not be possible to eat the food in the nose, it was always inconvenient to eat in the dark.It is very inconvenient to place the tin flashlight. You can't use the flashlight to shine in the sky when you are eating, right?You can't hold a flashlight by yourself, and the others eat, right?

Moreover, the straight light of the flashlight, even if it is placed horizontally on the side, also affects vision.

This portable lamp is different. Put it on the table like a teapot, lift the lampshade at the back, and use it just like the desk lamp with adjustable angle in later generations. It is very convenient and has soft light.

There are also many farmers who sometimes need to work in the dark in order to harvest food. They need a flashlight that is easy to place, high brightness, and long battery life.

Therefore, this product was sold out as soon as it was launched.

In the previous life, this portable lamp came out relatively late. In those few years, people's living conditions improved rapidly, and the power supply quickly stabilized. These made it only popular for a while, and soon disappeared like a flash in the pan.

And this time, it has been popular for at least ten years!
Jingyun Battery also thoughtfully marked the maintenance precautions of this portable lamp on the back of the portable lamp in order to make it last longer.
